I shut down my TrueNAS machine for a day and now it won't boot. Video included.

I have no partitions visible on both boot SSDs according to Minitool Partition Wizard so I don't know how else to get the configuration file.

You did not read or maybe understand the thread. The configuration file is saved on your pool.

That is very interesting. Yes, I did not read the link you sent because I saw no partitions on my boot drives. When I get back home I will definitely look into that now that I know the configuration is saved on the pool drives. This is valuable info you just told me! Thank you. When I recover the configuration file and apply it to my newly installed single SSD Core installation, am I able to at that time somehow put back my 2 Kingston drives and mirror the single SSD install onto them?

So I returned from my trip. First thing I did was restore the 2 pools to original state using a new single SSD and now everything is running 99% back to the way it was. The only thing I haven't configured yet is my battery backup to shut down the system if it enters a power failure and is on low battery level condition. I checked my original boot drives again on another different computer and they show as unallocated which is still unbelievable to me. TrueNas appears to be an excellent software for a DIY file server according to YouTube and the web in general. I still would like to know how a simple shutdown will make 2 mirrored drives disappear. If anyone has seen this before or something similar let me know so I won't make the same mistake again. Maybe mirroring is a weak point in the software? I have no clue. I will give this thread some time, see if anyone chimes in with anything interesting and then decide if I should mirror the boot drives again. At least now I have an idea what it takes to recover TrueNas if the system decides to self destruct again.
